Esfenvalerate

Esfenvalerate is a synthetic pyrethroid insecticide such as Conquer, Onslaught and Evercide  which is used on a wide range of pests such as moths, flies, beetles, and other insects. Synthetic pyrethroids are man-made insecticides created to mimic the chemical properties of the naturally-occurring insecticide pyrethrum, which comes from the crushed petals of the Chrysanthemum flower. Synthetic pyrethroids, like esfenvalerate, are effective as active ingredients because they offer the added bonus of remaining effective for longer periods of time that true pyrethrums. Pyrethroids are a group of man-made pesticides similar to the natural pesticide pyrethrum, which is produced from chrysanthemum flowers.
